Application ledAugust (20, 1915. Serial No. 46,475:

. To all whom z' may' concern.'

Be it known that I, HERMAN PARPERT, a citizen ofthe United-States,residing at St. Louis, State of Missouri, have invented certain new anduseful Improvements in Water- Heaters'of which the following is aspecication, reference being 4had therein lto the accompanying drawing.""My invention relates toimprovements in water heaters.

The object of my invention is to provide a water heater of the coiltypein which there Vis arranged a-burner atthe upper and lower ends ofthe coil so that the heat strikes both the upper and lower ends of thecoil and more quickly heats the water passing through the coil. fAnother object of my invention is to provide a water heater ofk thischaracter in which the upper burner is formed as an extension ofthelower burner, and the gas is supplied to the two burners through a sin-4 gle mixing tube.

A still Vfurther object of my invention is to prov-ide a simple, cheapand more eective burner adapted to 'be used in combination with a coilwaterheater, and having certain details ofstructure and combination ofparts hereinafter more Vfully -setl lforth.

In the accompanying drawings',

Figure 1 is a side elevation of the heatery showing one portion thereofopen, and showing the coil and burner in vertical section.

rFig. 2l is an enlarged vertical sectional viewpartlyl `broken away andtaken at right angles to Fig. 1.

Fig. 3 is an enlarged perspective view of the burner showing 'the burnercap removed and showingthe gassupply for the burners.

Referring now to the drawings, 1 represents the casing which iS of thevusual structure formed of two'sections2 'and` 3 hinged together at 4,and whereby Vaccess may be readily had to lthe coil as fully shown linFig. 1 of the drawings. of the casing 2 and 3 are preferably providedwith an inner lining 4, which is spaced from the outer casing and whichex-I tends approximately from the lower end of the coil to the upper endof the coil so that the excessive heat therefrom will not come in directcontact with the outer casing, and therefore, will not warp or disgurethe enamel on the outside of the outer casing.

The coil 5 enters through the lower end The two sections` of the casingat a point 6, and extends up.- wardly in a conical form and passes .out-Ward'ly from the casing at the point 7. IEX- tending across the upperend of 'the .coil is aplate 8 which is adapted to .deflect the fra-mefrom the upper burner and cause it tospread outl andengage the.convolutions of the upper end of the coil. While I hwe shown the coil 5within the casing, it will be understood that thesamecould be in thelforni of a thin double wall cylindricalalember forming a vertical watercolumn, and 1n the claimsfor convenience, I havepused the word ,.wat ercolumn Vwhich would cover the' coils.

4While I have shown this coil arranged yin a conica-l form, it will beunderstood .that the same could be arranged in a cylindrical form.without departing from my invention. The burner 9 is arrangedconcentrcally within the casing, and lhas its lower face Hush with Vthelower face of the .casing and is supported therein by a bracket 10carried by the lower end of .the casing which extends inwardly, and isprovided kwith'a slot 11 through which the ear 12 passe/S, and passingthrough the ear is a VCotter-pill 13 which Vengages the lower face ofthebracket 10 and supports thebu'rner in a horizontal position. By thisarrangement it will be seenthat the `burner is removably supported andcan be replaced or 4removed for cleaning passes and at which point it isburned. .One

side ofthe ring of the burner fhas a .downwardly extending tube 17 whichcommuni# cateswith thetrough 14 and .by .means of which gas is suppliedt0 the trough 14 and travels Varound andv is dischargedY through theopening 16 in the burner head around its entire periphery. The tube l17is provided with a set screw 18 by means of which the mixing tube 19 is,secured therein. The mixing tube extends downwardly and has a flaredlower end 20 provided with a usual shutter, and a gas supply pipe 21enters the flared end of the tube 19 and is controlled by the valve 22as fully shown in Fig. 3 of bis.

ranged upwardly extending lip which has secured therein an upwardlyextending elongated tube 26 which has an open upper end 2T at a point ashort distance below the deflecting plate 8. This burner tube 26 issupplied with gas from the trough 1st through the passages 23 and 24,and whereby the ri ng-lilre burner supplies the center burner with gasand but a single gas supply is required.

l/Vhile l have shown and described this specific means of forming twoburners with a central burner connected to the main burner by thetransverse passages 23 and 2l, it will be understood that the same couldbe Yaried without departing from my invention.

lly having the burner of the ring-like form, it will be seen that air issupplied through the center of the burner and also around its outerperiphery so that the necessary air is supplied to the burner head tocause the perfect combustion of the gas as it passes from the opening16.

By the construction herein shown and described it will bc seen that thecoil is heated at its lower end by the burner l5, and the additionalburner QG heats the Vupper end of the coil and the deflector plate 8prevents the heat from the upper burner from passing directly upwardlythus retarding it and causing a more thorough heating of the upper endof the coil.

Having thus fully described my invention what l claim and desire tosecure by Letters Patent is:

l. A water heater comprising a casing, a wat-er column therewithin, amain burner for the lower end of the water column and formed of a'ring-like member having inwardly extending passages communicating withthe burner, and a second burner supported by the inwardly extendingpassages and receiving its fuel supply from the main burner, the. secondburner extending upwardly within the water column and a baille plate atthe upper end of the water column.

Q. A water-heater comprising a casing, a lining therefor spaced apartfrom the casing, the said casing and lining formed in two parts andhinged together, a tubular water column extending upwardly inside of thesaid lining, a. main burner for the lower end of the water column formedof a ring.- lihe member, a second tubular burner Supported by the mainburner and receiving its :fuel supply therefrom, the said tubular burnerextending upwardly within the water column and having its upper endbelow the upper end of the water column and a baflie platelarranged atthe upper end of the water column and directly above the upper end ofthe tubular burner.

3. A water heater burner comprising a main burner formed of a ring-likemember for the lower end, of a water column, inwardly extending passagescommunicating with the burner and an upwardly extending tube carried bythe said passages and forming a second burner and receiving its fuelsupply from the main burner through the passages, the second burner forthe interior of the column.

l. A water heater burner comprising a main burner formed of a' ring-likemember for the lower end of the water column and having an open upperend, a removable burner head closing the ring-like main burner, inwardlyextending passages communicating with the main burner, an upwardlyextending nipple carried by the said passages and communicating with thesame, an upwardly extending tube supported by the nipple and forming asecond burner receiving its fuel supply from the main burner through thepassages and opened at its upper end, the sec-ond burner for heating theinterior of the water column.

5. A water heater comprising a water' Copies of this patent may beobtained for five cents each, by addressing the Commissioner o' Patents,Washington, D. C.
